In the testcases, the kernels scheduled on queues 11, 12, 13, 14 have data dependencies on, respectively, 'b', 'c', 'd', and 'e', as they write to them. However, they also have a data dependency on 'a' and 'N', as they read those. Previously, the testcases exited 'a' on queue 10 and 'N' on queue 15, meaning that it was possible for the aforementioned kernels to execute and to have 'a' and 'N' pulled under their feet. This patch adds waits for each of the kernels onto queue 10 before freeing 'a', guaranteeing that 'a' outlives the kernels, and the same on 'N'. libgomp/ChangeLog: * testsuite/libgomp.oacc-c-c++-common/data-2-lib.c (explanatory header): Fix typo. (main): Insert waits on kernels reading 'a' into queue 10 before exiting 'a', and waits on kernels reading 'N' into queue 15 before exiting 'N'. * testsuite/libgomp.oacc-c-c++-common/data-2.c: Ditto.
